ALTERNATOR AND STARTER TESTER WITH CAPACITIVE ELEMENT, ACTIVE LOAD CONTROL AND BELT SLIP DETECTION

A diagnostic system configured to test the performance of a vehicle component may include a processor configured to process test information from the vehicle component and control the vehicle component to be tested. The system may also include a memory configured to store the test information of the vehicle component and software that operates the vehicle component and a capacitive element configured to supply power to perform the testing of the vehicle component, wherein the memory and the capacitive element are in communication with the processor. The system may further include a monitoring module configured to monitor a power supply provided to perform the testing of the vehicle component and cuts off the power supply when the power exceeds a predetermined threshold. The diagnostic system further includes a sensor configured to sense the output voltage of the alternator and ensure that the diagnostic tool is properly operating the alternator component.
